Answer:
x = -1 y = 2
Step-by-step explanation:
Notice that the coefficients of x are opposites of each other. That makes the problem so much easier to solve. All you have to do is add the two equations and the x terms will be eliminated.
2x - 4y = -10
<u>-2x - y = 0</u>
- 5y = -10
y = 2 Substitute y = 2 into the first equation. 2x - 4(2) = -10
2x - 8 = -10
2x = -2
x = -1
It is always a good idea to check your results into the equations to see if they satisfy the equations.

<span>A = {odd numbers between 0 and 100}
</span><span>A = {1, 3, 5, 7,...., 95, 97, 99}
B = </span><span>{numbers between 50 and 150 that are evenly divisible by 5}
B = {50, 55, 60, 65, ..., 140, 145, 150}
The notation </span><span>A ∩ B means the set of items that are in set A and also in set B. In terms of venn diagrams, it's the overlapping region between circle A and circle B
In this case, the following values are found in both set A and set B
{55, 65, 75, 85, 95}
So that's why
</span>A ∩ B = <span>{55, 65, 75, 85, 95}
which is the final answer</span>
Answer: 6
Step-by-step explanation: Division use a calculator 12/2
Answer:
total surface area of cone is πr (r+l)
22/7 x 3 (3+4)
22/7*3 (7)
22 x 3 ( as 7 that was divided by 22 was cut out with 7 in the bracket)
hence,
TSA of cone = 66pi
